Which device is most likely to be used for calculating imagery in 3D space?

• CPU

• Cache

• SSD

• GPU

Which form of SSD has the fastest transfer rate?

• IDE

• PCI-E

• SATA

• USB

Answer explanation

PCI-Express transfersither via PCI add in card or M.2 NVME connector are the fastest as they provide drect coms with the CPU

Which of the following is NOT a benefit of Mechanical Hard disks

• Longer life when used for continual writing than SSD

• Faster throughput than SSD

• Cheaper per unit of capacity than SSD

• Generally available in larger capacities than SSD

Answer explanation

Whilst technically SSDs are available in very high capacities, mechanical drives are much more readily available in large capacities as the costs of high capacity mechanical drives is relatively low. High capacity SSDs are so expensive they are considered specialist items and are hard to source.
